Abstract

Australian marsupials have been distinct from eutherlans for about 130 million years (McKenna, 1969). Adaptive radiation during this time has resulted In considerable variety In ecological niche and anatomical features of marsupials. The relationship of the urinary and genital tracts to each other and the relatively undeveloped state of young, (born after a short gestation period) are among the major features distinguishing marsupials from eutherlans (Tyndale-Blscoe, 1973).
